According to current case law, the architect must produce a permanently approvable design. To this end, he must take into account, in addition to the requirements of the current state of the art, all public law regulations relevant to the construction project. The fact that the approval authority grants a permit does not relieve the architect, especially if the permit is later revoked due to defects in the design.
The now available BGH ruling makes it clear that this case law is fully applicable to the new approval procedures with a reduced scope of examination. In particular, the architect must ensure compliance with all public law regulations relevant to the construction project, even if the building authority only examines public law regulations to a limited extent.
